The purpose of the present paper was to study clinical, morphological and immunological aspects of late rejection of renal allotransplants. We have, therefore, analyzed the occurrence and nature of renal transplant disease and graft failure among 125 recipients surviving for 1 to more than 8 years after transplantation. In this population transplant disease as defined by the appearance of heavy proteinuria and/or steadily declining graft function occurred in 22 patients. At the closure date of the study on December 31, 1972 complete graft failure had occurred in 12 of these 22 patients and 4 of these have died. In addition two patients died in the presence of normal graft function, due to chronic hepatitis and metastatic cancer respectively. As based on clinical findings, pathophysiological features and renal lesions the patients with late transplant disease were classified into two groups and described accordingly. Group A, termed glomerular transplant disease, included a majority of 16 patients, constituting a rather homogenous idsease entity in relation to course of disease, clinical findings and renal lesions as studied by light-, immunofluorescence- and electron microscopy. All these patients presented with heavy proteinuria, which was non-selective in all but two, resulting eventually in complete loss of graft function in eight cases. All these patients developed hypoalbuminemia and hypercholesterolemia, and one half manifested a classical nephrotic syndrome. Arterial hypertension occurred in all patients except two. Glomerular structure as studied by light microscopy revealed a number of lesions of a rather polymorphous pattern in all patients in group A. Endomesangial proliferation, hyperplasia and segmental proliferation of epithelial cells and thickening of capillary walls were prominent features, although the degree of severity, extension and type of lesion occurred in such varying proportions that classification into any well characterized category of glomerulonephritis was not possible. All cases in group A revealed immune deposits, most frequently containing IgG, IgM, complement and fibrinogen. IgA, IgD and IgE were also demonstrated in a lesser proportion of cases in this group. The immunofluorescent pattern was a mixed granular and linear, and in no case strictly linear or granular alone. The ultrastructural investigation contains a detailed analysis of the

A case of squamous cell carcinoma of the tongue in a 26-year-old man developing nine years after renal transplantation is presented. This is the first such case to be reported. Within seven months, widespread tumor metastases resulted in death. Pathologic examination of the transplanted kidney demonstrated neither re-establishment of glomerulonephritis nor evidence of rejection, and lack of significant renal disease was confirmed by electron microscopy. This long term survival without development of renal pathology is also of great interest.

A series of cases is presented which illustrates unusual aspects in the presentation, diagnosis, and management of renal cell carcinoma. The entire "classic triad" of flank pain, gross hematuria, and palpable mass was not present at the time of diagnosis in any of the patients. Moreover, in only three patients did the initial clinical findings raise the suspicion of renal cell carcinoma. A diagnosis of polycystic kidney disease, cardiac failure, glomerulonephritis, analgesic abuse, and perirenal hemorrhage obscured the primary diagnosis in the other five patients. In four patients the tumor was probably present from 3 to 12 years before detection. These findings emphasize that knowledge of the hematologic, humoral, immunologic and vascular abnormalities induced by this tumor may provide a clue to early diagnosis. The systematic use of excretion urography, nephrotomography, ultrasonography, renal scanning, renal arteriography and cyst puncture then may allow the accuracy of radiologic diagnosis of this tumor to approach 100%. Lastly, the therapy of choice for this tumor is radical nephrectomy. Excision of apparently solitary metastases also may sometimes be feasible. However, partial nephrectomy to remove tumor in a solitary kidney was performed in one patient to avoid the need for end-stage kidney treatment. Where nephrectomy renders the patient anephric, chronic hemodialysis and renal transplantation should be considered as potential measures to sustain life. While hormonal agents, chemotherapy, and radiation therapy sometimes provide palliation, their use generally has been disappointing.

The Drash syndrome, the first case in Thailand is reported. The patient had male pseudohermaphrodite, Wilms' tumor of the left kidney and mesangial proliferative glomerulonephritis. Metastasis of Wilms' tumor was noted in the liver, omentum, pelvic peritoneum and vertebral body. Chemotherapy (actinomycin D, vincristine and dexamethasone) and local irradiation were given. The patient developed pneumonia, diarrhea and ended up with Steven-Johnson syndrome from Cotrimoxazole hypersensitivity.

To evaluate the influence of [2-(3-carboxy-1-probylthio)-4-methyl-1,3-thiazole]acetic acid (tiprotimod, HBW 538) on the host defense mechanisms, a number of experimental studies in different animal models were performed. The prophylactic treatment of NMRI mice with tiprotimod significantly prolonged the mean survival time of the animals after intravenous infection with Candida albicans 200/175 and increased the resistance to the fungal infection to 180% in comparison to controls. In vitro the drug showed no direct fungistatic or fungicidal activity. In an experimental model of persistent systemic candidiasis Balb/c mice infected intravenously with Candida albicans were treated with the immunomodulator tiprotimod after the fungal colonization of kidney was manifested (3 days post infection). The treatment of the mice after the infection resulted in a reduction of the infectious load and the abscess formation in kidney as well as in a decrease of numbers of yeasts in the urine. In the syngeneic B16 melanoma tumor model tiprotimod significantly prolonged the medium survival time and reduced the number of visuable metastases in the lungs even when applied after resection of the primary tumor graft. Tiprotimod also beneficially influenced the course of the disease in two murine graft-vs-host models (hemolytic anemia and immune complex glomerulonephritis) which lead to a B cell mediated autoimmune disease with fatal outcome. The application of the drug in the induction phase mitigated the development of the diseases and prevented animals from dying.(ABSTRACT TRUNCATED AT 250 WORDS)

Histologic and immunofluorescence studies of the kidneys of mice bearing a progressive melanoma show a proliferative glomerulonephritis associated with immune complex deposition in the mesangium and along the glomerular basement membrane This immune complex disease is distinct from the age-associated disease of the C57BL/6J host strain and the complexes can be shown to consist of soluble tumor antigen and antitumor antibody. Furthermore, the intensity of IgG complex deposition correlates directly with tumor progress (size and metastases) and inversely with mononuclear leukocyte infiltration of the tumor. In vitro assays for lymphocyte cytotoxicity and humoral antibody were found to be less reliable indicators of tumor progress. The possible role of circulating soluble tumor antigen in modifying the immune response to tumors is discussed.

The remarkable history of the 1951 pp 66 year old woman with gastric adenocarcinoma is reviewed. After subtotal gastrectomy she survived for 22 years without any metastases. Presumably the artificially induced high titer IgG, anti-P1 proved to be cytotoxic in two stages: (1) binding of anti-P1 to the terminal fifth sugar, galactose, and (2) the action of cellular immunity in the form of killer T derived lymphocytes containing receptors for IgG molecules. An identical mechanism may be operative in inducing abortions in the pp pregnant woman with a P1 fetus. P1 illegitimate glycolipid (GL) red cell antigen and Forssman (Fs) tissue in adenocarcinoma suggest the self-nonself concept because these are genetically foreign to the host. This concept applies also to numerous "autoimmune" diseases such as RA, lupus, glomerulonephritis, Coombs positive hemolytic anemia and other diseases with immune complexes (ICs) of 20--22 Svedberg units deposited as lesions with tissue damage. In the presence of the GL antigens (ABO, P, Fs), the normal serum contains antibodies for the missing antigen(s). The predicted anti-Fs was present in about 80% of normal employees of ages 18--70. In cancer sera the incidence was 35--40%. On testing normal sera by age in terms of decades anti-Fs was present in 93% in the youngest, and only 55% in the oldest group. This may be associated with the gradual loss of protein synthesis with aging and/or the accumulation of soluble ICs which bind the C1q portion of the C added to the test mixture of heat-inactivated serum (1 : 8) g.p. C (1 : 30) and srbc. In "autoimmune" diseases there is an active immune response to viral or bacterial infections or infestations or drugs which attach to rbc and/or tissue cell membranes. This results in the deposition in selected organs of ICs of 20--22 S units with lesions and tissue damage. For therapy plasma (from young donors) exchange has been recommended to compensate for the loss of IgG antibodies and C.

A case of asynchronous renal carcinoma with a 15-year course is described. Right nephrectomy and left heminephrectomy were performed. Solitary metastases to pancreas and striated muscle were treated with total pancreatectomy and local excision, respectively. The patient died of renal failure due to progressive immune complex glomerulonephritis, which was documented histologically as well as by clinical observations of intensifying excretion of urinary protein with decreasing selectivity. The glomerular lesion is suggested to have been caused by deposition of tumour-related immune complexes arising from an immune response by the host to his tumour.

A patient with carcinoma of the prostate and metastases developed the nephrotic syndrome following hormonal therapy. A decrease in the dose of estrogens was associated with decreased proteinuria, but when therapy was increased the nephrotic syndrome became more severe. Renal biopsy performed when proteinuria was present showed subendothelial electron dense deposits, complement by immunofluorescence, and a morphologic pattern of membranoproliferative glomerulonephritis. There was evidence of resorption of the deposits by endothelial cells. Microspherical particles resembling those described in prostatic cancer were found in the glomeruli. On the basis of previous reports it is concluded that circulating tumor antigen-antibody complexes produced glomerulonephritis, the severity of which was related to the amount of soluble antigen released by tumor cell destruction. Apparent phagocytosis of immune complexes by glomerular endothelial cells was believed to account for the reversibility of the nephrotic syndrome. The role of the virus-like particles in the process is as yet unclear.

Different adhesion molecules are involved in the maintenance of tissue architecture, morphogenesis, immunosurveillance, inflammation, tumour growth, etc. Thus, this review will be directed to the role of cadherins, selectins, integrins and members of the immunoglobuline supergene family in the pathogenesis of glomerulonephritis, acute renal failure, reaction of renal rejection, development of renal tumours, their invasion and metastases. A better understanding of the role of adhesion molecules in nephropathology may provide new aspects of treatment of different forms of renal diseases including tumours.
